Problems solved by technology

According to the structural characteristics of the axial flow fan, the air volume is proportional to the speed, and the wind pressure is proportional to the square of the speed. Therefore, the increase of the wind pressure is limited.
If a multi-stage counter-rotating structure in series is adopted to increase the wind pressure of the axial flow fan, the overall size of the equipment will be quite large and the cost will be high.

Abstract

The invention relates to a mobile multi-stage hydraulic-drive pneumatic spray dust-settling truck, mainly solving technical problems of high investment caused by individual use of spray dust-settling devices and poor effect caused by common use of the spray dust-settling devices due to far distance on conditions of multiple and dispersed dust source points, variable dust source locations and complicated conditions of dust sources. The technical scheme includes that a water storage tank is connected with a high-pressure water pump through a water pipe and high-pressure water is pumped to a spraying assembly; a hydraulic station is connected to a hydraulic motor of a mist spraying device through a high-pressure oil pipe to drive an impeller of axle-flow fans to generate high-pressure air flows, the high-pressure air flows send mist to a dust working face, and high-pressure oil of a hydraulic station is connected to a hydraulic cylinder; the mist spraying device is lifted and then is driven to oscillate around a rotating bearing by a motor and a reduction gearbox via a rotational driving gear; a carriage engine drives a power generator through a double-output transmission in a gear shifting manner so that power required for system running is obtained. The mobile multi-stage hydraulic-drive pneumatic spray dust-settling truck is mainly used for far-distance large-range dust settling and removing and firefighting in fugitive emission fields such as tunnel heading, blast mining, loading, crushing and unloading.

Description

technical field [0001] The invention relates to an environmental protection dust suppression vehicle, in particular to a mobile multistage hydraulic transmission air spray dust suppression vehicle which utilizes a mobile multistage hydraulic motor to drive a fan to realize long-distance and large-scale wind delivery of water mist. Background technique [0002] At present, some dust is often generated in the production process of industrial and mining enterprises. In order to avoid affecting the surrounding environment and protect the health of employees, it is necessary to use various means to control the dust. For relatively concentrated and fixed dust points, dust collection hoods are usually used to capture the dust, and the dust gas is sucked to the dust removal system through the pipeline for purification and then discharged. However, due to the limitation of production conditions in more occasions, the dust points are scattered. Some dust spots are also mobile. Such...
